Title: Length measuring device for long magnetic wire
Inventor: TAKAHASHI HIDEO
IPC: G01B7/04
Filed: 1979-06-20
Abstract: PURPOSE: To measure length precisely by detecting length measuring errors caused by velocity fluctuation, tension fluctuation and temperature changes.  
     CONSTITUTION: Each time a main magnetic mark detector 18 detects a magnetic mark on wire 1, a length measuring counter in a microprocessor 20 counts it, and if the counted value reaches a length to be measured ordered from a keyboard, a stop instruction is outputted from the microprocessor 20 to a feeder 12 and a winder 14 and the running of the wire 1 is stopped. While measuring, the microprocessor 20 stores measuring errors owing to velocity deviations from a standard velocity from the keyboard 56, measuring errors owing to tension deviations from a standard tension and expansion errors owing to temperature deviations from a standard temperature. The measuring errors owing to velocity, tension, temperature, etc., are displayed on a display device 58. After adding the total of the measuring errors, a visual mark is put manually or automatically.

Title: Seal type double row angular ball bearing
Inventor: KUBOTA YOSHINOBU
IPC: F16C19/18
Filed: 1995-03-31
Abstract: PURPOSE: To provide an increased life of grease by a method wherein the height of a shoulder between raceway grooves is set to a value lower than a shoulder height on the two end part side at least at one of outer and inner rings. CONSTITUTION: By reduction of the thickness of a shoulder part 1b between the raceway grooves 1a of an inner ring 1, the shoulder height h1 thereof is set to a value lower than the shoulder heights h2 of the shoulder part 1c on the two end part sides, and the shoulder height h2 is set to the same height as that of a conventional bearing. Thereby, the volume of the internal space of a bearing is increased by an amount equivalent to reduction of the shoulder height h1 . Thus, a grease sealing amount is increased as the efficient of grease sealing is maintained at the same value as that of a conventional bearing, resulting in provision of an increased life for grease. Further, since the shoulder height h2 is the same as that of a conventional bearing, there is no fear of moment resistance being reduced.
